DETAILED DESCRIPTION

In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the following described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, other embodiments obtained by those skilled in the art without creative efforts are fall within the scope of protection of the present application.

The present application imbeds the support for parallel grid computing into the kernel of the language, and provides operators or keywords for parallel grid computing, such that the user can specify the code to run in parallel, and the data of the variables used in the specified code and the parallel code are automatically formed the task of parallel grid computing.

As shown in FIG. 1, which shows a schematic flowchart of a method for code execution provided by an embodiment of present application, the method can include:

Step S101, judging, during execution of a target code, whether there is a preset parallel processing identifier in a current code statement to be executed.

In the present embodiment, the parallel processing identifier may be composed of a specified symbol and/or keyword. For example, the symbol “#” may be selected as the parallel processing identifier.

If the parallel processing identifier does not exist in the current code statement to be executed, which indicate that there is no need to perform parallel processing on the current code statement to be executed, in this case, steps S102 and S104 are executed. If the parallel processing identifier is in the code statement, which indicates that the current code statement to be executed needs to be processed in parallel, and in this case, steps S103 and S104 are executed.

Step S102, executing the current code statement to be executed in a serial processing mode.

That is, according to the processing method in the prior art, only after the execution of the current code statement to be executed is completed and the result is returned, the next code statement will continue to be executed.

Step S103, distributing a task to be processed indicated by the current code statement to be executed to a preset grid computing system for multi-thread parallel processing.

The grid computing system includes more than two compute nodes. In the present embodiment, the task distribution and result return may be performed through a preset task distributor, which may be a single-machine multi-thread implementation or a multi-machine parallel network calculation.

In the process of task distribution, the task distributor needs to maintain load balance of each compute node. For example, the current number of tasks of each compute node in the grid computing system may be obtained respectively, and then calculating the number of tasks that can be processed by each compute node according to the current number of tasks of each compute node and a preset threshold of the number of tasks of each compute node; and finally distributing the task to be processed to the compute node with a largest number of tasks that can be processed for processing.

Preferably, the algorithm shown in FIG. 2 may be used to achieve load balancing in the task distribution processing:

Step S1031, acquiring a current number of tasks of each compute node in the grid computing system, respectively.

The current number of tasks includes the number of tasks being processed and the number of tasks waiting to be processed.

Step S1032, calculating the number of tasks that can be processed by each compute node according to the current number of tasks of each compute node and a preset threshold of the number of tasks of each compute node.

The threshold of the number of tasks can be determined by the computing power of each compute node, and the two are positively correlated.

For example, the faster the processing speed of the compute node's CPU, the higher the corresponding threshold of the number of tasks, otherwise, the slower the processing speed of the CPU of the compute node, the lower the threshold of the corresponding threshold of the number of tasks.

The number of tasks that can be processed by a compute node may be the difference between the threshold of the number of tasks of the compute node and the current number of tasks of the compute node.

Step S1033, acquiring historical task processing records of each compute node within a preset statistical time period, respectively.

The statistical time period can be set according to the facts. For example, historical processing records of the previous month, the previous week, or the previous day can be taken for statistics, which is not specifically limited in this embodiment.

Step S1034, counting a first duration of each compute node when a processing state is normal, and a second duration of each compute node when a processing state is abnormal according to the historical task processing records.

The processing state being abnormal means that the task distributor receives abnormal feedback of a compute node or the compute node does not respond within a timeout.

Summing the processing time of a compute node when a processing state is normal to obtain the first duration of the compute node, and summing the processing time thereof hen a processing state is abnormal to obtain the second duration of the compute node.

Step S1035, calculating a reliability of each compute node according to the first duration and the second duration.

The reliability is used to characterize the stability of a compute node during the calculation process. The reliability of a compute node is positively related to its first duration and negatively related to its second duration. For example, the ratio of the first duration to the total duration may be used as the reliability, where the total duration is the sum of the first duration and the second duration.

Step S1036, calculating a priority of each compute node according to the number of tasks that can be processed and the reliability.

The priority being positively related to the number of tasks that can be processed and positively related to the reliability. For example, a first coefficient corresponding to the number of tasks that can be processed and a second coefficient corresponding to the reliability may be separately set, calculating a first product of the number of tasks that can be processed and the first coefficient, and a second product of the reliability and the second coefficient, and then calculating the sum of the first product and the second product, the larger the calculated sum, the higher the priority.

Step S1037, distributing the task to be processed to the compute node with the highest priority for processing.

It should be noted that the above process is only a feasible task distribution method, and other task distribution methods can also be selected according to actual needs, which is not specifically limited in this embodiment.

Step S104, determining a next code statement after the current code statement to be executed as a new current code statement to be executed.

After determining the new current code statement to be executed, it returns to step S101 until the target code is completely executed.

The present application can be used for large-scale distributed computing, implemented in a scripting language interpreter or a compiled language compiler, which can be used for parallel computing in a single machine, and can be applied to multiple machines in multiple machines parallel grid computing. For scripting languages, the user can directly submit the source code of the script and the required variables as tasks. For compiled languages, the user can choose to compile the code that needs to be parallelized into binary code that can be distributed and submitted, and submit it as a task together with the data. The user can also use the JIT mode, which submits the code and data to be compiled together as a task.

In this embodiment, a unified function source code center is provided, and subprograms called in parallel grid computing can be obtained through the unified source code center, and when the source code changes, the module providing parallel grid computing is notified in time. Using this method for parallel grid computing, the development is very convenient. From the perspective of the developer, there is no need to understand tasks and task decomposition methods, and it does not rely on parallel method libraries. It can be applied to the development of various unspecified parallel grid methods. In addition, the task of grid decomposition does not require any deployment, and can be developed and used at any time, and modified and run at any time.

In summary, the embodiments of the present application provide an identifier for parallel processing, and the user can use the parallel processing identifier to identify code statements that need to be processed in parallel in advance. During the execution of the code, when the parallel processing identifier is found in the current code statement to be executed, the task to be processed indicated by the current code statement to be executed is distributed to a preset grid computing system Perform multi-thread parallel processing. During the execution of this code statement, you can continue to execute the next code statement. When processing code that involves a large number of complex operations, you can make full use of the calculations of each compute node in the grid computing system. The ability to process tasks in parallel greatly shortens the code execution time and improves processing efficiency.

Embodiment 2

As shown in FIG. 3, a schematic flowchart of a method for code execution is provided, the method can include:

Step S301, judging whether there is an input variable whose data type is a preset grid computing type in the current code statement to be executed during the execution of the target code.

The grid computing type is a data type that requires multi-thread parallel processing in the grid computing system. In the present embodiment, the data type of grid computing is added to the data type of the language for storing parallel computing. When the language accesses the data type, such as assignment, operation, serialization, etc., it blocks to wait for the end of the parallel grid computing contained in the data. If the parallel computing is completed, the return value of the parallel grid computing is recorded in the data type.

If there is an input variable whose data type is the grid computing type in the current code statement to be executed, step S302 and subsequent steps are executed, and if there is no input variable whose data type is the grid computing type in the current code statement to be executed, step S305 and subsequent steps are executed.

Step S302, acquiring a current processing state of the input variable.

In the present embodiment, the processing state of the variable of the grid computing type includes a completed state and an incomplete state, where the incomplete state includes states such as waiting for submission, submitted, and errors. The processing state of grid computing type variables is used to describe the state of parallel tasks, and to record the necessary information for the execution of tasks in the submission state, which is used to terminate and resubmit tasks and so on.

Step S303, judging whether the current processing state of the input variable is an incomplete state.

If the current processing state of the input variable is an incomplete state, step S304 and subsequent steps are executed, and if the current processing state of the input variable is a completed state, step S305 and subsequent steps are executed.

Step S304, waiting for a preset duration.

The duration can be set according to the actual needs, and in particular, it can also be set to 0, that is, without waiting.

After waiting for the duration, return to step S302 until the current processing state of the input variable is the completed state.

Step S305, judging whether there is a preset parallel processing identifier in the current code statement to be executed.

If the parallel processing identifier does not exist in the current code statement to be executed, step S306 and step S308 are executed, and if the parallel processing identifier is in the current code statement to be executed, step S306 and Step S307 are executed.

Step S306, executing the current code statement to be executed according to the serial processing mode.

Step S307, distributing the task to be processed indicated by the current code statement to be executed to a preset grid computing system for multi-thread parallel processing.

Step S308, determining a next code statement after the current code statement to be executed as a new current code statement to be executed.

After determining the new current code statement to be executed, it returns to step S301 until the execution of the target code is completed.

The process from step S305 to step S308 is the same as step S101 to step S104 in the first embodiment. For details, please refer to the description in the first embodiment, and it is not repeatedly described herein.

FIG. 4 is a specific example of parallel grid computing.

In this example, the symbol “#” is used as the parallel processing identifier, and the parallel grid computing is performed on the method after “#”, and the program will continue in parallel when the result of the grid computing is not used until the result of the grid computing is accessed.

Specifically, in the formation of the array c, each step has nothing to do with the result of the previous grid computing, so parallel grid computing can be performed independently of each other. Here, a specific parallel “for” is not required. Through the using of the parallel processing identifiers, the traditional “for” has done a job similar to the parallel “for”. The “subProc” is used to the data contained in the variable “i” by “#”, and the code called by “subProc” form a task and submit it to the task distributor, and the grid computing type is putted into the array c. When accessing “c”, such as summing “sum” or standard deviation “stddev”, it will wait for the end of the grid computing task contained in “c”, and d:=#sum(c) and e:=#stddev(c), since both depend directly on “c” but can be parallel to each other, such that the task of values of “sum” and “c” are placed in “d” grid computing type, and the task of values of “stddev” and “c” are placed in “e” grid computing type, and submitting two tasks to the task distributor, therefore, these two tasks are concurrent, and when returning the result of “d/e”, it will wait for the end of the two grid computing types “d” and “e”.

Preferably, the method for code execution may further include an exception handling process. Once an error occurs in the task execution unit, the task transfer is allowed. Specifically, the current processing state of each compute node in the grid computing system can be obtained, and if there is a compute node in the grid computing system whose current processing state is abnormal, the unprocessed task of the compute node whose current processing state is abnormal is transferred to the compute node whose current processing state is normal to continue processing.

The number of concurrent can also be set in the task distributor to prevent the number of concurrent from exceeding the limit. In this way, the task distributor can choose to queue or reject the overrun task.

Preferably, a task management mechanism can also be provided to check the state of parallel grid task assignment on the management side, allowing the manager to perform tasks such as task termination.

In summary, based on the first embodiment, the embodiments of the present application add a processing mechanism that the parallel grid computing is automatically blocked and waited during resource access, and the accessing always in parallel when there is no blocking of the parallel grid resources. This design allows nesting of parallel grids, and the number of parallel grids is not limited.
